Comparison of efficacy of topical clindamycin and nicotinamide combination with plain clindamycin for the treatment of acne vulgaris and acne resistant to topical antibiotics.

A total of 75 patients with inflammatory acne vulgaris were divided into three groups. Group A was treated with combination of 4% nicotinamide and 1% clindamycin combination, Group B was treated with plain 1% clindamycin and Group C which was considered to have resistance to local antibiotics due to no response to treatment was treated with the combination. At the end of 8 weeks the results were compared. It was concluded that addition of nicotinamide was of not much value in treating inflammatory acne and results were some as for plain clindamycin and also the combination did not offer much relief in treatment of resistant acne.

Calcinosis cutis.

A 22-year-old male patient presented with multiple swellings over elbows and knees and a sinus over the right elbow discharging chalky white material. Skin biopsy of the swelling demonstrated calcium deposition in dermis and subcutis. There was no evidence of connective tissue disorder or abnormal mineral metabolism. Hence it was concluded as idiopathic calcinosis cutis and is reported for its interesting presentation.
